Since 2022 was the first election after redistricting, and changes in many states between that and 2024 meant lines have been or are going to be redrawn (like in NC) many of our data sources will not have accurate district boundaries. You are looking for boundaries for the 118th Congress (2022) or the 119th Congress (2024). This may make doing research on districts a bit trickier. Meet with Roz Tedford or Morgan Ritchie-Baum for help on doing data research on new districts!
